learning 3 Flashcards
whats a variable ratio reinforcement
where a response is reinforced after an unpredictable number of responses
- unpredictable relationship
whats continuous reinforcement
where desired behavior is reinforced everytime it occurs
whats primary reinforcement
a stimulus that inherently satifies biological needs
- do not require learning to be reinforcing
whats secondary reinforcement
- refers to a stimulus that becomes reinforcing through its association with with a primary reinforcer
- do not inherentley satisfy biological needs but acquire reinforcing properties through learned associations
- e.g saying ‘good dog’ when giving a dog a treat
dixon et al., 2014 study on gambling
- found low winnings make noise associated with positive value (example of a secondary reinforcer)
- found gamblers over estimated their winnings 28 times out of 200 reality
whats the issue with a negative consequences with behaviour
- may produce a generalised inhibiting effect
- doesnt reinforce a preferable behaviour
what is avoidance learning and what 2 types of conditioning it uses
- use of classical and operant conditioning
- associates stimulus with something unpleasant, learns to avoid/ escape it through a behaviour
how did rat deal with shock
- the light (initially neutral) asscoated with shock (unconditioned stimulus) due to discomfort
- causes conditoned response (fear to shock)
- operant conditioning continues behaviour to turn lever on when light turns on
tolman andHonzzik 1930 study of rats getting out maze
- blue, given reinforcement when exited maze, errors made dropped overtime
- green, never given reinforcement or reward, errors made reduced slightly
- red, not given reinforcement till day 11, saw marked improvement and reductions in errors made
what did study of rats in maze show in absence/presence of reinforcement
in group red, indicated same amount of learning happened in first 11 days however did not exhibit in behaviour until reward
observational learning
- does not incooperate reinforcement or punishment to individual, not immediately characterised within stimulus response
shettleworth 2010 after GOULD 1994 study with black birds
- big bird alongside naive black bird
- when experienced black birds see predator tend to ‘flap and squak’
- naive bird copied this action but to a stuffed toy instead
- shows social transformation of predator recognition
